Ophthalmologists are prone to musculoskeletal disorders due to their hunched posture when operating a surgical microscope. True Posture aims to provide insights on posture when using a 3D microscope visualization system in contrast to a traditional surgical microscope. True Posture implements a system that measures the electrical activity produced by skeletal back muscle while performing surgery using electromyography (EMG) sensors. The data collected from these sensors is used to provide insights on the surgeon's musculoskeletal state.
